Protect Every Megawatt-Hour

Delayed or duplicated generation data skews forecasts and triggers costly storage overcorrections. Expanso validates telemetry at each site, so dispatch and curtailment decisions reflect actual output.

No hardware replacement. No changes to existing inverters or controllers.

Distributed generation without distributed validation is operational guesswork

When generation data from dozens of sites arrives late, duplicated, or incomplete, every downstream system - forecasting, storage dispatch, curtailment - operates on distorted inputs. The revenue impact compounds across every site, every hour.

Forecast models optimize against delayed inputs from remote sites

When a solar farm's inverter data arrives 30 seconds late, the forecast model treats the stale readings as current. The resulting dispatch and curtailment decisions don't match reality. Storage charges when it shouldn't. Viable generation gets curtailed.

1-5%
revenue leakage per MWh

5-15% duplicated data makes intermittency look worse than it is

Retransmitted inverter readings enter your analytics as separate observations. Output appears to spike and dip when the equipment was generating steadily. Investors and regulators see volatility that doesn't exist.

Storage dispatch based on stale readings wastes capacity

When the dispatch system sees delayed generation data, it charges storage to compensate for a dip that already resolved. By the time the real data arrives, the battery cycle has been wasted.

Curtailment misfires waste viable generation output

Curtailment logic that operates on incomplete data windows cuts generation that the grid could have absorbed. Each misfire reduces revenue and erodes PPA performance metrics.

Generation data integrity, enforced at every site

Expanso validates every inverter reading, nacelle metric, and storage dispatch signal at the source. Your forecast models, dispatch systems, and grid operators only receive data that passes validation.

# Edge validation output - solar farm cluster 9
inverters: 96/96 reporting
duplicates: 31 removed
irradiance: within 0.5%
generation: complete window
storage_soc: time-aligned
grid_freq: nominal range

What we validate

Inverter completeness - every unit in the cluster reporting before data is forwarded

Duplicate suppression - retransmitted readings stripped at the site before aggregation

Cross-site timing - generation data from all sites aligned before dispatch consumes it

Storage SOC accuracy - state of charge validated against dispatch commands

What your systems receive

Time-consistent generation data across all sites in the portfolio

Deduplicated streams that reflect actual generation, not retry artifacts

Complete data windows so curtailment logic operates on full information

Latency flags when site data exceeds freshness thresholds

Large-Scale Deployment

14,847 distributed endpoints. 4.7 PB/month. Edge-first validation at scale.

A major U.S. deployment across 14,847 endpoints validated Expanso's approach to edge-first data integrity. Processing moved to points of presence, raw data stayed local, and only metadata and flagged events flowed upstream.

Data Volume
4.7 PB/month 47 GB + 230 GB flagged
99%+ reduction in upstream volume
Data Retention
7 days 5 years
260x longer retention
Investigation Time
3 days 4 hours
94% faster investigations

"Isn't this what our data platform already does?"

Your platform aggregates generation data from across your solar, wind, and storage sites. It stores it, visualizes it, and feeds your analytics. But it doesn't verify that every inverter reading and dispatch signal is complete, time-consistent, and free of duplicates before it arrives.

Expanso validates at each site before aggregation. Your forecasts, dispatch decisions, and curtailment logic all operate on inputs that reflect what's actually happening in the field.

Built for renewable operations

Vendor-agnostic across all inverter and controller types

Deploys site by site across wind, solar, and storage

No hardware replacement or firmware changes required

No disruption to generation or dispatch operations

Why teams deploy Expanso

Cleaner forecasting inputs improve generation predictions

Fewer storage overcorrections from delayed data

Higher confidence in regulatory and investor reporting

Scales across every site in your portfolio

Every megawatt-hour you can't verify is revenue you can't protect

Validate at every site. Protect every megawatt-hour.
